2.2 John is driving his 1 200 kg car along a concrete highway during a heavy storm. The road is very wet and his tyres slide along the road. 2.1 If the kinetic friction force is 6 000 N, calculate the coefficient of kinetic friction between the tyres and the road. If the coefficient of friction is 0,8 when the highway is dry, determine the ratio of the force of kinetic friction exerted on the tyres by the dry road compared to the wet road.
